WEB-HOLDER.

Specification of Letters Patent.

Patented June 6, I916.

Application filed March 20, 1916. Serial No. 35,406.

I To all whom it may concern:

Be it known that I, LOUIS N. D. WILLIAMS, a citizen of theUnitedStates,residing in Ogontz, Pennsylvania, have invented certain Improvements inWeb-Holders, of which the following is a specification.

My invention consists of an improvement inweb holderssuch as areemployed in connection with the needle carriers of knitting machines orengaging the sinker wales of the last produced course of stitches andpreventing thes'aid stitches from rising with the needles.

My invention consists. in so constructing such web holders and theguides therefor as to prevent rise of the web holders under the upwardstress of the sinker wales, while, at the same time, the formation ofthe guides is facilitated and cheapened.

7 In the accompanying drawing Figure 1 is a sectional view, on anenlarged scale, of the upper part of the needle. carrier of a knittingmachine, with web holder and guide and retainer for the latterconstructed in accordance with my invention; Fig. 2 is a face viewlooking in the direction of the arrow, Fig. 1; Fig. 3 is a detachedperspective view of the web holder; Figs. 4 and 5 are views representingsuccessive steps in the formation of theweb holder guides in accordancewith my invention; Figs. 6 and 7 are views similar to Fig. 5, butillustrating constructions which my invention is intended to replace;Figs. 8 and 9 are perspective views of modified forms of'web holder, inaccordance with my invention, and Fig. 10

' isa view similar to part of Fig. 2, but illustrating a modification ofmy invention.

My invention is applicable either to circular or straight bed knittingmachines, but will, for convenience, be considered as applied to acircular machine.

In the drawing, 1 represents part of the needle cylinder and 2a ringmounted upon the upper edge of said needle cylinder and having,projecting upwardly therefrom, ribs B, between-which are laterallyguided the web holders 4, each of the latter having at Y the bottom aforwardly projecting stem 5.

In producing the web holder guides in accordance with my invention Ifirst form in the inner face-ofa solid ring 2, a groove 2, as shown inFig. 4, and I then form in said ring vertical slots extending from thetop of the same down to the level of the base of the groove, asshown inFig. 5, so that each rib projecting upwardly from the ring 2 presents arelatively narrow neck 2 and an inwardly projecting head 2 the latterpresentingat the bottom a shoulder 2 The guide stem 5 of each web holderis notched,

will thus effectually prevent any rising movement of the Web holdersunder the upward stress of the sinker wales of the web. When the Webholders are constructed in this manner the guides therefor can bereadily produced by first turning ormilling the groove2, and then bysuccessive operations of a milling cutter y, as shown in Fig. 5,producing the vertical slots with intervening ribs 3, therebyconsiderably simplifying and cheapening the operation as compared withguides in which the vertical retention of the web holders is effected bycontact of their stems 5 with a ring 2 integral with the ribs 3, asshown in Fig. 6, or with a separate ring 2 bearing against the shoulders2?, as shown in Fig. 7 f

' Instead of forming the retainer on the guide stem 5 ofthe web holderin the manner shown in Fig. 3, other means of forming the same, withinthe scope of my invention, may be employed, for instance by bending alateral flange? on the top of the stem 5, as

shown in Fig. 8, or-bydoubling over upon itself, as shown at 7 in Fig.9, the projecting end of said stem 5.

Instead of laterally bending the inner portion of the stem 7 of the webholder the shouldered portion of the head 2 of the guide rib may be thusbent, if desired, in order-to overlap said stem 7, as shown in Fig. 10.

I claim:

1. A knitting machine web holder having a guide stem with laterallyprojecting flange, whose upper face will, by contact withan adjoiningmember of the machine, serve to prevent rise of said web holder. L

' 2." A knitting machine web holder having a laterally bent portionpresenting an upper a projecting'guide stem' part of. which is laterallybent and presents an upper face which, by contact with an adj oinin'gmember of the machine, will preventfrise ozt the'web" holder.

4. A knitting machine Webv holder having a projecting guide stem withvertical notch therein, that portion of the'steni inwardly beyond thenotch having itsnpper portion bent laterally. v

5. The combination ofa'knittifig machine upwardly projecting ribs andalternating slots, each of said ribspresenting a shoulder,j and Webholders having stems" inseam playing betvveen said. ribs, oneof saidparts having a laterally projecting member so as tocauseleckingengagement of said stems and shoulders. v V p 6. The combinationof a knitting machine needle carrier having a top Inemher with upwardlyprojecting ribs and j'alternating slots; each of said ribs presentingashoulder, and Web holders having guide stems playing between said ribs,and having laterally projecting fiangesfor bearing agalnstsaidshoulders. t

In testimony whereof, I have slgned my LOUIS N. D WILLIAMS.\Vitn'esses': s p
